public class PhpServletScriptEngine
A PHP script engine for Servlets. See ContextLoaderListener
for details.
In order to evaluate PHP scripts follow these steps:
EngineFactory
:
private static File script;
private static final File getHelloScript() {
if (script!=null) return script;
String webCacheDir = ctx.getRealPath(req.getServletPath());
Reader reader = new StringReader ("<?php echo 'hello from PHP'; ?>");
return EngineFactory.getPhpScript(webCacheDir, reader);
}
EngineFactory
:
ScriptEngine scriptEngine = EngineFactory.getPhpScriptEngine(this, ctx, req, res);
Reader readerHello = EngineFactory.createPhpScriptFileReader(getHelloScript());
scriptEngine.getContext().setWriter (out);
scriptEngine.eval(readerHello);
readerHello.close();
ScriptEngine e = EngineFactory.getPhpScriptEngine(this, ctx, req, res);
e.getContext().setWriter (out);
e.eval("<?php echo "hello java world"; ?>");
